To me the “boo” issue is somehow a way for Harry to remind everyone he’s still a child, to both unsettle them a bit more and make them more prone to forgive his impertinence.
Or maybe it’s not that calculated. After all, Harry is still a child, as smart and rationalist as he is, and it just pleased him to say “boo” and he didn’t think much about that part, not sure.
